Common Weakness Enumeration
CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9899 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-02-27 03:34 – Updated: 2025-02-27 18:31

Details
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/tracing: Fix a potential TP_printk UAF
The commit afd2627f727b ("tracing: Check "%s" dereference via the field and not the TP_printk format") exposes potential UAFs in the xe_bo_move trace event.
Fix those by avoiding dereferencing the xe_mem_type_to_name[] array at TP_printk time.
Since some code refactoring has taken place, explicit backporting may be needed for kernels older than 6.10.

Foxit PDF Reader AcroForm Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of Doc objects in AcroForms. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22808.
